Question
Determine the standard enthalpy change and std. Gibbs free energy change of
reaction at 400 k for the reaction
CO(g) +2H2(g) → CH3OH (g)
At 298.15 K, ∆Hf,CO (g)
0 = -26.41 kcal/mol, ∆Hf,CH3OH(g)
0 = -48.08 kcal/mol,
∆Gf,CO (g)
0 = -32.8079 kcal/mol, ∆Gf,CH3OH(g)
0 = -38.69 kcal/mol,
The standard heat capacity of various components is given by,
Cp
0 = a + bT + cT
2 + dT
3
, where Cp
0
is in cal/mol-K and T is in K
Component a b ×102 c ×105 d ×109
CH3OH 4.55 2.186 -0.291 -1.92
